While mild forms of hepatitis are common, the seriousness of the cases has alarmed health officials.
Health professionals in Europe and the United States are examining the first known cases of severe liver disease in children in the United Kingdom.
The European Center for Disease Control and Prevention (CDC) said on Tuesday that it had discovered an unknown number of cases of hepatitis in Denmark, Ireland, the Netherlands and Spain.
The United States has identified 74 cases of acute hepatitis in Alabama last week.
In a statement last week, World Health Organization (WHO) officials said:
Mild hepatitis B is common in children, and the severity of the cases has led to a halt by health officials.
“Hepatitis B is very common in children after various viral infections, but now it is very different,” says Graham Cook, professor of infectious diseases at Imperial College London.
Some cases in the UK require specialist care in the liver departments and a few require liver transplants. The nine infected children in the United States are between 1 and 6 years old. Two important liver transplants.
One of the most common causes of adenovirus infection in the United States has been identified by a group of scientists in the past.
Although some cases of coronavirus may be spreading, researchers are still looking for a link between the disease and COVID-19.
Meanwhile, British public health officials said it had nothing to do with covad-19 vaccines and that none of the injured children had been vaccinated.
The World Health Organization (WHO) says there has been no contact with affected children in the UK and no recent international travel.
Laboratory tests are being performed to determine if there is a chemical or toxin behind the disease.
